There's no built in feature to do this. The OnLogEvent handler also does not have access to those fields on the actions so there's no way to access it directly.
Your best bet is to write your own custom logging routine to include this information.
HOWEVER...
... logging all events fills up your log quickly. Technically speaking, a non-technical reader of the log doesn't need every mouse click or keystroke... they just need to know "We checked this... and it passed" or "we tried this... and it failed". As Marsha_R suggested, I think your better bang for the buck is to modify your tests to output relevant information that a non-technical user would need and log those items only rather than every "Event" test complete generates.
